On this episode we welcome Gemma Tillack, agribusiness campaign director of the Rainforest Action Network, which has been very active in the global campaign to protect Indonesia’s Leuser Ecosystem, one of the richest, most biodiverse tropical forests on the planet that is at risk of being turned into oil palm plantations. Tillack explains just what makes Leuser so unique and valuable and how consumers can help decide the fate of the region.

And in the latest Field Notes segment, research ecologist Marconi Campos Cerqueira discusses a recently completed a study that used bioacoustic monitoring to examine bird ranges in the mountains of Puerto Rico, which appear to be shifting related to climate change, and he’ll share some of his recordings with us.
